Integration Calculation
Your calculator performs integration using Gauss-Kronrod integration for approximation. The
calculator uses the following function for integration.
∫ (
A Syntax and Input
∫ ( f ( x ), a , b , tol )
f ( x ): Function of x (Input the function used by variable X.)
• All variables other than X are viewed as constants.
a : Lower limit of region of integration
b : Upper limit of region of integration
tol : Error tolerance range (Can be input only when linear display is being used.)
• This parameter can be omitted. In that case, a tolerance of 1 × 10
–5
is used.
Example:
∫ (ln( x ), 1, e ) = 1 ( tol value not input)
B
z – {MATH} 1(∫ dX)
